Uses for GaviLyte-N with Flavor Pack

Polyethylene glycol (PEG) and electrolytes combination solution is used to cleanse the colon (bowel) before a medical test (eg, colonoscopy).

PEG-electrolyte solution is a laxative. It works by causing you to have diarrhea to clean your colon. Cleaning your colon will help your doctor see the inside of your colon more clearly during colonoscopy.

This medicine is available only with your doctor's prescription.
